I'm not even going to attempt to explain the nuances of pull starting a car. I know it's difficult and only works for the manual transmissions I've never learned how to drive (embarrassing, I know). That's why I wouldn't try my hand at pull starting, especially with a bus added to the equation.
These Russians clearly don't know what they're doing, but their lack of knowledge doesn't dissuade them. One of the men ties the car to a public bus without any visible sign of permission. As the bus gets going both dudes realize it might have been a good idea to get in the car. Frantically trying to hop in, the two can do nothing to stop their whip from being towed right into the back of another car.
It's like a real-life Three Two Stooges. The only difference is that instead of silence, we're treated to the soundtrack of onlooking girls laughing at the display of idiocy in front of them.
